Pet peeve - people who need to talk to me RIGHT AWAY, so they IM, text, email, and call (yes, all 4) over and over, as fast as possible. I get back to my desk after an hour long meeting and have 20 voicemails (and IMs, and texts, and emails)! Do people not understand what leaving a message is - that I will get back to you AS SOON AS I AM AVAILABLE! JFC, I am just a data person - I'm not saving lives, or catching bad guys, or anything. I run data, and people use it for analysis. Waiting a few hours makes no difference at all.
